The Novelle Clip-on Raised Toilet Seat will provide a 75mm (3") raise to the existing toilet seat and thus an overall raise of 100mm (4"). With no brackets to attach the Clip On Raised Toilet Seat is very easy to fix to the toilet and can be quickly attached directly onto the toilet seat itself rather than the bowl, making it convenient and ideal for travel purposes. Simply squeeze together the open "horseshoe" section, locate the front clip underneath the existing toilet seat, push down and release the open section. To remove the seat, simply reverse the process releasing the rear clip first. The Novelle Clip On Raised Toilet Seat can be autoclaved at up to 80 degrees for maximum hygiene.Product Specification:One Novelle Clip On Raised Toilet SeatProvides a total raise of 100mm (4")Clips directly to the toilet seatNo brackets mean very fast to fitIdeal for taking on holidays etcLight and comfortable to useCan be autoclaved at up to 80 degreesSeat height: 75mm (3")Aperture size: 275mm x 240mm (11" x 9.5")Maximum user weight: 190 kgs (30 st)
